Pete Davidson is turning over a new leaf thanks to the immense support of his loved ones ... and he's getting professional help as well.

Our sources say Pete's been overwhelmed by all the love and it's lifted his spirits ... and he plans to be back on 'SNL' when it returns in mid-January.
We broke the story ... Davidson was really in a dark place last weekend when he posted an ominous note suggesting he wanted to die, and he even believed his friends and colleagues didn't care about him. We're told what spun him into that dark place was Ariana Grande's tweet seemingly making fun of mental health issues.
Pete now realizes ... his friends and family do indeed care about him ... a lot.
As for his ex-fiance, Ariana Grande, being turned away by security when she rushed to comfort him ... we're told it's because he was hurt by what she tweeted.
